How we tested spoilage

We tested spoilage in a commercially bottled Italian salad dressing that had been stored in our pantry at room temperature, around 70°F (21°C). After holding the unopened bottle for 365 days, we opened it and inspected the contents. We noted a slight separation of ingredients, which was not unusual, but we also detected an unpleasant odor that was markedly different from its original scent. The dressing appeared somewhat darker than expected, and the texture had become slightly thicker. To verify its safety, we heated a small sample to 165°F (74°C), but given the concerning observations, we decided to discard the entire bottle to prioritize safety.
